Or tango's httpclient; I think I know how I'm just not sure that when you call read with the delegate and length will read call the delegate and supply the array of specified length and do so until it gets through or will it read that length and stop and wait for you to call read again.
If anyone has an example with HttpClient and the delegate read thing I described I'd love to see it.  If it does require to call read more than once, how do you check that you have read everything and there is nothing more to read.
